This past weekened ripped up Engineered Hardwood from concrete subfloor. There must of been a sale on Urethane glue when installed cause they used it on every single inch of +300 sqft. Not all the glue came up with the floor scraper though. Getting ready to put a floating bamboo floor down and using an foam underlayment with moisture barrier film. Have some SLC spots that need to be fixed from the use of the floor scraper but 2 questions.
